ABSTRACT:
A manual operation mode specifying a fixed speed change ratio by manual operation is set in a continuously variable transmission for a vehicle which continuously varies a speed change ratio to an arbitrary target speed change ratio. The manual operation mode defines for example first speed-fourth speed. While a driver is accelerating at the specified speed change ratio, the speed change ratio is decreased when a predetermined vehicle speed is reached. A difference of speed change ratio when the driver performs a shift-up operation after this decrease is thereby reduced. As a result, there are fewer drops of engine rotation speed due to shift-up, and acceleration performance is improved.
